DETAILED DESCRIPTION

In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of some example embodiments. It will be evident, however, to one skilled in the art that the present disclosure may be practiced without these specific details.

Disclosed herein are systems and methods that provide a vision-based robot control system. Consumer-level robots are becoming a reality with lower cost manufacturing and more affordable electronics. Robots may include various sensors to detect their environment. Example sensors include proximity sensors, position sensors, impact sensors, and cameras or other image-based sensors. While some robots are able to be controlled using buttons on an exterior housing, with remote control devices, or with auxiliary controls, such as controls at a charging station, what is needed are more intuitive ways to control robots.

FIG. 1 is a diagram illustrating a robot 100 operating in an environment 102, according to an embodiment. The robot 100 may be any type of self-propelled, mobile machine. The robot 100 may use various apparatus to move, such as wheels, treads, tracks, or the like. The robot 100 may also implement one or more legs to hop, walk, crawl, or otherwise move (e.g., fly) about an environment. The robot 100 may include an onboard camera system, which may include one or more cameras. The camera system may include a visual light camera (e.g., an RGB camera), an infrared (IR) light camera, or other cameras. The IR camera may be used for night vision, as a depth camera, or thermal imagery. In addition to a camera system, the robot 100 may also be equipped with other sensors, such as a sonar system, radar system, etc. to navigate environments. The robot 100 also includes one or more communication systems, which may include a wireless networking communication system. The wireless networking communication system may use one or more of a variety of protocols or technologies, including Wi-Fi, 3G, and 4G LTE/LTE-A, WiMAX networks, Bluetooth, near field communication (NFC), or the like.

Alternatively, the robot 100 may interface with one or more cameras 104A, 104B, 104C, 104D (collectively referred to as 104). The cameras 104 may capture a user's movement, actions, or other aspects of the user 106 as the user 106 moves about in the environment 102. Cameras 104 in the environment 100 may include visible light cameras, infrared cameras, or other types of cameras. The cameras 104 may be connected using wired or wireless connections. In addition, one or more of the cameras 104 may use one or more servos for pan and tilt to follow a subject while it is within the operating field of view of the camera 104. The camera 104 may track a subject using shape recognition or with a physical marker that the subject holds or wears and the camera 104 actively tracks. The physical marker may be wireless connected to the camera 104 using a technology such as Bluetooth. Although only four cameras 104 are illustrated in FIG. 1, it is understood that more or fewer cameras may be implemented based on the size of the environment, obstructions in the environment, or other considerations. Combinations of onboard cameras and environmental cameras may be used.

The user 106 may interface with the robot 100 using various intuitive techniques. In an aspect, the user 106 gestures in a particular manner, which may then be captured by the cameras 104 or the robot 100, or by other environmental sensors. The gesture may provide instruction to the robot 100 based on a preconfigured association. For instance, the user 106 may mark a spot on the floor by tapping his foot in a prescribed manner The robot 100 may be a cleaning robot, such as semi-automated vacuum. The tapping may be detected by the user's motion using cameras 104, by sound processing (e.g., using a microphone array), by vibration (e.g., by using in-floor sensors to detect vibration location), or by other mechanisms or combinations of mechanisms. After receiving an indication of the gesture performed by the user 106, the robot 100 may concentrate in the area indicated by the gesture, such as by performing extra passes or by temporarily slowing down to clean the area more thoroughly.

It is understood that while some embodiments discussed in this disclosure include camera and image processing, other modalities of gesture detect may be used instead of, or in combination with, camera and image processing techniques. Thus, gesture detection is used to identify a particular location to perform a robotic action, and as such, in some cases, the gesture is used to intuitively identify the location (e.g., pointing to a spot on the floor, motioning to an area, or tapping the floor with a foot, etc.).

In another aspect, the user 106 may provide instructions using a marker with an infrared-detectable ink. The ink is not visible to human eyes, so it does not discolor or mar materials, such as carpet or furniture upholstery. The robot 100 may be configured with an IR camera, or the environmental camera 104 may be an IR camera, which is able to see the markings left by the user 106. Different markings may be used, such as a box to indicate an extra clean, a circle to instruct the robot 100 to use a different cleaner, or an “X” to avoid an area. Other markings may be used. In another aspect, the robot 100 may clean the IR-detectable ink when cleaning the marked area. As such, the ink marking may act as a one-time instruction. Alternatively, the IR-ink may be left behind purposefully, so that the mark is able to be observed on subsequent cleanings.

In addition to visual ques, the user 106 may also provide instruction with other modalities, such as verbally or with geolocation. In an example, the user 106 may gesture and then speak a verbal command, which is received at the robot 100 and then acted upon by the robot 100. For instance, the user 106 may point to a spot on the floor with a laser pointer and speak “move the shelf over here.” The robot 100 may directly receive such commands with an onboard camera system and a microphone. Alternatively, environmental sensors, such as cameras 104 and microphones, may detect the user's actions and communicate them as commands to the robot 100. Upon receiving an actionable instruction, the robot 100 may move to the shelf, lift it, and then move it to the location indicated by the user's gesture.

In another aspect, the user 106 may use a geolocation as an additional input. For instance, the user 106 may use a mobile device 108 (e.g., smartphone, tablet, wearable device, etc.) and perform a gesture while holding or wearing the mobile device. The user 106 may also initiate verbal commands to the mobile device. The location of the mobile device 108 (e.g., geolocation) may be obtained and transmitted to the robot 100 along with an instruction, as defined by the gesture or verbal instruction provided by the user 106.

FIG. 2 is a flowchart illustrating the data and control flow, according to an embodiment. A triggering action performed by a user is observed by a camera system (operation 200). For instance, a user may perform a gesture or leave a mark visible to the robot (e.g., with a token or with an ink visible to the camera system that may or may not be visible to unaided humans) The camera system interprets the action (operation 202). The interpretation may include gesture recognition, pattern recognition, shape recognition, or other forms of analysis to determine the type of triggering action performed by the user. If the triggering action is recognized, then additional processing may occur to determine whether the user provided any other triggering commands (operation 204), such as a verbal command If a verbal command is recognized, for example, then the verbal command may be parsed and used in the subsequent operations. Additionally, geolocations, locations of pointing gestures, or other commands, may be analyzed at operation 204.

A lookup table is referenced (operation 206) to determine which operation the robot is to perform based on the trigger input. The types of trigger input and resulting robot operations may differ according to the design and function of the robot. For example, a cleaning robot may be programmed to respond to certain triggering actions, where a security robot may be programmed to respond to other triggering actions. In the case where several robots operate in the same environment, the user may map the triggering actions to only trigger one of several robots. Alternatively, the user may configure the commands such that a single command may cause multiple robots to perform certain functions.

If the triggering actions map to an action found in the lookup table, then the robot is scheduled to perform the resulting operation (operation 208). The robot may perform the operation immediately or may be configured to perform the operation at the next duty cycle (e.g., the next cleaning cycle).

If the triggering actions are not found in the lookup table, then the control flow returns to operation 200, where the system monitors for additional user triggering actions.

FIG. 3 is a block diagram illustrating a vision-based robot control system 300 for controlling a robot, according to an embodiment. The system 300 may be installed in a robot. Alternatively, the system 300 may be separate from a robot, but communicatively coupled to the robot in order provide control signals. The system 300 includes a camera system interface 302, a trigger detection unit 304, an operation database interface 306, and a transceiver 308.

The camera system interface 302, trigger detection unit 304, operation database interface 306, and transceiver 308 are understood to encompass tangible entities that are physically constructed, specifically configured (e.g., hardwired), or temporarily (e.g., transitorily) configured (e.g., programmed) to operate in a specified manner or to perform part or all of any operations described herein. Such tangible entitles may be constructed using one or more circuits, such as with dedicated hardware (e.g., field programmable gate arrays (FPGAs), logic gates, graphics processing unit (GPU), a digital signal processor (DSP), etc.). As such, the tangible entities described herein may be referred to as circuits, circuitry, processor units, subsystems, or the like.

The camera system interface 302 may receive camera signal information from a camera array, which may be installed on the system 300 or be remote, but communicatively coupled to the system 300. For instance, the camera system interface 302 may receive raw video signal information or processed signal information (e.g., compressed video signals). In another aspect, the camera system interface 302 may be used to receive tagged information from a camera array, which analyzed and preprocessed the raw video signal at, or near, the camera array.

Trigger detection unit 304 is capable of analyzing image or video data received by the camera system interface 302, and detect and identify a gesture exhibited by movements performed by a person in the image or video data. The trigger detection unit 304 determines whether the movements constitute a recognized gesture. If the movements do constitute a recognized gesture, the trigger detection unit 304 may trigger operations performed by a robot.

To detect the gesture, the trigger detection unit 304 may access image data of an arm, finger, foot, or hand motion of a user captured by a camera system, and identify the gesture based on the image data. The image data may be a number of successive images (e.g., video) over which the gesture is performed.

In another aspect, the trigger detection unit 304 accesses depth image data of an arm, finger, foot or hand motion of the user and identifies the gesture based on the depth image data. The depth image data may be a number of successive images (e.g., video) over which the gesture is performed.

In another aspect, the trigger detection unit 304 operates independent from the camera system interface 302, and receives information or data that indicates a gesture via a different pathway. For example, in an aspect, to detect the selection gesture, the trigger detection unit 304 is to access motion data from an auxiliary device, the motion data describing an arm, finger, foot, or hand motion of the user and identify the gesture based on the motion data. The auxiliary device may be a mobile device, such as a smartphone, a wearable device, such as a smartwatch or a glove, or other type of device moveable by the user in free space. Examples include, but are not limited to, smartphones, smartwatches, e-textiles (e.g., shirts, gloves, pants, shoes, etc.), smart bracelets, smart rings, or the like.

The operation database interface 306 is used to determine whether the gesture is detected and recognized as being a triggering gesture. If it is a recognized triggering gesture, then commands are transmitted to a robot using the transceiver 308. The transceiver 308 may be configured to transmit over various wireless networks, such as a Wi-Fi network (e.g., according to the IEEE 802.11 family of standards), cellular network, such as a network designed according to the Long-Term Evolution (LTE), LTE-Advanced, 5G or Global System for Mobile Communications (GSM) families of standards, or the like. When the system 300 is incorporated into a robot, then the commands may be directly communicated to a robot controller by way of a wired connection.

Thus, the system 300 describes a vision-based robot control system, the system 300 comprising the camera system interface 302, the trigger detection unit 304, and the transceiver 308. The camera system interface 302 may be configured to receive image data from a camera system/

In an embodiment, the image data includes a non-visible marking made by a user, the non-visible marking acting as the triggering action. In a further embodiment, the non-visible marking comprises an infrared-visible ink marking. In another embodiment, the non-visible marking is a symbol, and to initiate the robot operation, the operation database interface 306 is used to access a lookup table and search for the symbol to identify a corresponding robot operation.

In an embodiment, the trigger detection unit 304 is to obtain a geolocation associated with the triggering action and the transceiver 308 is to initiate the robot operation to be performed at the geolocation. In a further embodiment, the geolocation is obtained from a device operated by a user performing the triggering action. In another embodiment, the geolocation is obtained from a gesture performed by the user, the gesture captured in the image data.

The non-visible marking may be infrared ink, as described above. Thus, in an embodiment, the non-visible marking comprises an infrared-visible ink marking. Various words, symbols, or other indicia may be made with such ink and the robot control system may decipher the indicia and determine the meaning of the command Thus, in an embodiment, the non-visible marking is a symbol, and initiating the robot operation comprises searching a lookup table for the symbol to identify a corresponding robot operation. The lookup table may be administered by the user, or by an administrative person, such as the manufacturer or provider of the robot and related services.

In an embodiment, the method 400 includes obtaining a geolocation associated with the triggering action and initiating the robot operation to be performed at the geolocation. The geolocation may be obtained in various ways, such as with a mobile device that is able to determine a global positioning system (GPS) location (or similar), or by a camera system able to track and determine the user's location when the user performs a gesture or leaves a marking. Thus, in an embodiment, the geolocation is obtained from a device operated by a user performing the triggering action. In another embodiment, the geolocation is obtained from a gesture performed by the user, the gesture captured in the image data.
